WINDMILL.

Application filed June 29, 1914, Serial No. 847,847.

To all whom it may concern:

Be it known that 1, ALBERT F. Gnonon, a citizen of the United States, formerly residing at Salina, in the county of Saline and State of Kansas, and now residing at ()assville, in the county of Barry and State of Missouri, have invented a certain new and useful Improvement in Windmills, of which the following is a specification.

My invention relates to improvements in windmills.

My invention is adapted for use in connection with a windmill provided with one Or more windwheels carried on a single tower.

One of the objects of my invention is to provide novel governing means for controlling the throwing of the windwheels into or out of the wind.

A further object of myv invention is to provide novel driving mechanism for connccting the windwheels with the reciprocaing pitman usually employed to transmit the power.

My invention provides still further novel mechanisn'i for automatically engaging and holding the main vane in the out oil the wind position.

Another object of my invention is to pro vide novel auxiliary main mechanism for swinging the windwheel support out of the wind when the wind pressure becomes too great.

{)ther novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawings, which illustrate the preferred embodiment of my invention,

Figure 1 is a rear elevation of my improvement applied to a windmill of the two windwheel type.

Fig. 2 is a side elevation of the same.

Fig. 3 is an enlarged detail view, partly in side elevation and partly in vertical section, showing the beam of the main vane locked in the out of the wind position and seated against the spring cushion provided therefor on the revoluble support.

tween the main vane and the revoluble support.

Fig. 7 is an enlarged horizontal sectional View on the line 77 of Fig. 1, showing, the crank pin mounted in one of the driven sprocket wheels, a portion of which is shown.

Similar reference characters designate similar parts in the different views.

1 designates a tower of the usual construction having mounted on the top thereof a horizontal base member supporting balls 3, which in turn support a member at which is centrally secured to a horizontal rectangular frame 5, which with the member l constitutes a wind'wheel support having a vertical axis.

Two sets of bearings 6 are mounted on the frame 5 and have respectively rotatably mounted therein two horizontal parallel shafts 7 secured respectively to two windwheels 8.

ltespectively secured to the shafts 7 are sprocket wheels 9 which are respectively connected by two chain belts 10 to two sprocket wheels 11 which are respectively rotatably mounted on two horizontal studs 12 disposed in alinemeut with each other parallel with the shafts 7 and respectively mounted in bearings 13, which are secured to the top of the member l, with the studs 12 disposed, preferably, at one side of the axis 01" the frame 5.

A. pitman 1 1 has its lower end pivoted to a vertical reciprocating member 15, which may be employed to transmit power to a pump or other mechanism, which it is de signed that the windmill shall operate.

The upper end of the pitman 14 is pivoted to a horizontal crank pin 16, Fig. 7, opposite ends of which are respectively mounted and radially adjustable in radial slots 17 pro vided one in each of the sprocket wheels 11. For releasably locking the crank pin 16 in the position to which it may be adjusted, its opposite ends are screw-threaded and have respectively mounted thereon nuts 18 adapted to bear against collars 19 mounted on the crank pin 16 and having projections 20, which are adapted to enter notches 21 provided in each sprocket wheel 11 at opposite sides of the slot 17.

By radially adjusting; the crank pin 16, the stroke of the pitman 1d and that of the member 15 may be changed.

hen the wind wheels 8, which are arranged to drive in like directions, are driven by the wind, the pitman 14 and member 15 will, be reciprocated by means of the crank pin 16, sprocket wheels 11, chains 10, sprocket wheels 9 and shafts 7.

For adjusting the tension of the chain belts 10, the two sets of bearings 6 are adjustable on the frame 5 toward and from the axis thereof. As a preferred means of fecting this adjustment, set screws 22 respectively mounted in vertical projections 23 on the upper side of the frame 5, between the bearings 6 and the axis of the frame 5 respectively bear against the inner ends of the bearings 6.

Said bearings are secured to the frame 5 by bolts 24, which are mounted in longitudinal slots 25 provided in the frame 5, as shown in Fig. 4. The set screws 22 have screw-threaded engagement with the projections "23, so that by turning said screws in the proper direction after loosening the bolts 24, the bearings 5 may be moved toward the ends of the frame 5, thereby tightening the belts 10.

A main vane 26 having a horizontal beam 27 is pivoted at the inner end of said beam to a vertical bolt 28 which extends through the two horizontal rearwardly projecting portions 29 and 30 of the windwheel support. The member 29 is secured to the upper side of the frame 5, and the portion 30 is disposedbelow the member 29 and is an extension of the member 4, see Fig. 6.

The vane 26 is normally swung to the into the wind position, relative to the frame 5 and windwheels 8, shown in Figs. 1, 2 and 4, by means of a coil spring 31, one end of which is secured to a laterally extending arm 32 of the beam 27, the other end of the spring being secured to a chain 33, which in turn is secured to an eye 34 fastened to the frame 5.

For preventing the vane 26 from being swung past the position shown in Fig. 4, the vane beam 27 has secured to it a chain 35, which is connected to one end of a coil spring 36, the other end of which is connected to an eye 37 secured to the frame 5 at the'side of the pivot bolt 28 which is opposite to the side'to which is secured the eye 34.

When the vane 26 is in the position shown in Fig. 4, the tension of the spring 36' em ceeds that of the spring 81, thereby holding the vane from being swung to the right beyond the position shown in Fig. 4.

For manually retracting the vane 26 to the out of the wind position relative to the frame 5, and as shown in Fig. 3, the beam 27 has secured to it a rope 38 which passes aroundthe pulley 39, mounted on the frame 5 adjacent-to the left end thereof, as shown in Fig. 4, the rope 38 passing thence over a pulley 40 mounted on the member 4, and thence downwardly through a hole 41 provided in the member 4. The rope 38 is sufiiciently long to be reached from the ground.

, When the rope 38 is pulled so as to draw the beam 27 to the out of the wind position, shown in Fig. 3, said beam will engage and. lift the rear end of a latch 42, which is gravity actuated, and which is pivoted at its forward end to a horizontal bolt 43 secured to the left end of the frame 5, as viewed in Fig. 4.

To lift the latch 42 so as to release the beam'27, said latch has secured to it a rope 44, which passes from the latch 42 upwardly over a pulley 45 mounted on the frame 5, said rope passing thence over a pulley 46 carried by the member 4, thence passing downwardly through the hole 41 to a point adjacent to the ground.

For cushioning the beam 27 when it is swung into engagement with the latch 42, I provide a vertical plate 47 which is adapted to be struck by the beam 27, and which is slidably mounted on twohorizontal bolts 48 extending rearwardly from and secured one above the other to the frame 5, as shown in Fig. 3.

The plate 47 bears against the rear ends of two coil springs 49 which respectively encircle the bolts 48 and have their forward ends bearing against the frame 5. The bolts 48 have their rear ends provided with nuts 50, which prevent the springs 49 forcing the plate 47 off from the bolts 48.

For swinging the wind wheels 8 out of the wind when the wind pressure becomes too great, I provide an auxiliary vane 51, which is rigidly secured to the outer end of a horizontal shaft 52, which is disposed at right angles to the shafts 7, and which is pivotally mounted in bearings 53, which are secured to the forward side of the frame 5.

The shaft 52 has secured to it and extending laterally therefrom a radial arm 54 on which is slidably mounted a weight 55,v which is adapted to be secured on the arm 54 in the position to which it may be adjusted by a set screw 56.

The relative arrangement of the vane 51 and the arm 54 on the shaft 52 is such that the weight 55, will normally hold the vane 51 in a position inclined to the horizontal, as shown in Fig. 5.

A radial pin 57 securedto the shaft 52 V prevents the weight 55- from swinging to the vertical position, and retains the'vane 51 in the inclined position shown in solid lines in Fig. 5.

When the wind pressure becomes suiiicient, it will swing the vane5l to the vertical position shownin dotted lines in Fig. 5, with the arin54disposed horizontally.

ill)

A radial pin 58 secured to the shaft 52 is adapted to strike the frame 5, so as to prevent the vane 51 being swung by the wind past the vertical.

When the vane 51 has been swung to the vertical position, the force of the wind acting thereon will swing the frame 5 and windwheels 8 out of the wind.

As best shown in Fig. 2, and in Fig. 4, the vane beam 27 has secured to it one end of a brace rod 59, the other end of which is secured to an eye bolt 60, which is secured to a plate 61 fastened to the top of an inverted V-shaped brace 62, the arms of which are secured to the frame 5.

Forwardly and downwardly extending braces (53 have their upper ends secured to the brace 62 and their lower ends secured to the frame adjacent to the forward side thereof.

The eye bolt 60 is preferably disposed to the right, as viewed in Fig. of the axis of the vane 26, which axis is the longitudi, nal center of the bolt 28.

By the location of the eye bolt 60 above the pivotal connection of the beam 27 with the frame 5, and at the right side of the axis of the vane 26, as viewed in Fig. 4, when the said vane is being swung from the position shown in Fig. 4: toward the out of the wind position, the rear end of the vane will be lifted or swung upwardly, the pivotal connection of the beam 27 with the bolt 28 being sufficiently loose to permit of this upward movement, whereby the weight of the vane 26 and the beam 27 will resist the swinging of the vane from the position shown in Fig. l, and will assist the spring 31 in swinging it to said position.

By adjusting the weight 55 lengthwise on the arm 54;, the pressure required to swing the auxiliary vane 51 to the vertical position may be varied.

I do not limit my invention to the structure shown and described, as modifications, within the scope of the appended claims, may be made without departing from the spirit of my invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is

1. In a windmill, a rotatable support, a windwheel rotatable thereon, a driven memher rotatable on said support having a radial slot and a row of radial notches at one edge of the slot, a crank pin radially adjustable in said slot and adapted to bear against said driven member, a clampingmember mounted on said crank pin and adapted to enter said notches, a nut on said crank pin adapted to bear against the clamping member to hold it in said notches, and driving means connecting the windwheel and said driven member.

2. In a windmill, a rotatable support, two

windwheels rotatable thereon, two crank disks rotatably mounted on said support, a crank pin having threaded ends and extending through and radially adjustable in said crank disks, means including two nuts mounted on said threaded ends respectively of said crank pin for clamping the latter to said two disks, a pitman pivoted to the crank pin between said disks, and driving means respectively connecting two windwheels with said two crank disks. 3. In a windmill, a rotatable windwheel support, a vane pivoted thereto, a cushion carried'by said support and against which the vane is adapted to be swung, and a latch pivoted to said support and adapted to re leasably engage the vane for holding the latter against said cushion.

4. In a windmill, a rotatable support, a vane pivoted thereto, two bolts secured to said support, a plate slidable on said bolts and adapted to be struck by said vane, yielding means for resisting the movement of said plate by said vane, and a latch .for releasably holding the vane against said plate.

In a windmill, a rotatable windwheel support, a vane pivoted thereto, and two means attached to the vane and attached respectively to the support at opposite sides of the vane and includig each a coil spring for respectively swinging the vane in opposite directions, one of the springs being stronger than the other.

In testimony whereof I have signed my name to this specification in presence of two subscribing witnesses.
